powerpc: Introduce toreal/fromreal assembly macros On 32-bit platforms, these convert from kernel virtual addresses to real (physical addresses), like tophys/tovirt but they use the same register for the source and destination. On 64-bit platforms, they do nothing because the hardware ignores the top two bits of the address in real mode. These new macros are used in fpu.S now. Signed-off-by: Paul Mackerras <paulus@samba.org>
